The following data represent the pH of rain for a random sample of rain dates in Tucker County, West Virginia. A normal probability plot suggests the data could come from a population that is normally distributed. A boxplot indicates there are no outliers. In Problem 31 from Section 9.2, we found a 95% confidence interval for the mean pH of rainwater in Tucker County, West Virginia.
